Proceedings of the 23rd international conference on World wide web, 2014 The development of Semantic Web (RDF) brings new requirements for data analytics tools and methods, going beyond querying to semantics-rich analytics through warehouse-style tools. In this work, we fully redesign, from the bottom up, core data analytics concepts and tools in the context of RDF data, leading to the first complete formal framework for ...

Semantics for Analytic Containment [PDF]
Studia Logica, 2004 The notion of analytic containment introduced by R. B. Angell provides a kind of relevant implication whose main feature is that a disjunction is not always implied by its component. The extension of analytic containment by this usually admitted axiom on disjunction gives, in fact, rise to the relevant implication of Anderson and Belnap, which is ...
